[0002] At present, the workpiece roll needs to be stamped three times through three sets of molds to produce the shape. First, the edge of the workpiece is pre-bent into a 1 / 2 circle. In order to facilitate the pre-bending of the surrounding area, two sets of side shaping molds are used to complete the pre-bending, and then the roll is used. After the mold is completed, the 1 / 2 circle is formed. This production method has the following disadvantages in the production process: because the whole process of forming needs to use three sets of molds, it can be completed by stamping three times. There are many processing procedures, low production efficiency and long production cycle. , high labor intensity and high production cost
